1 Claim.

This invention relates to air conditioning means, the general object ofthe invention being to provide inexpensive means for washing and coolingthe air in a building by forcing air through a casing by a fan andcausing the air passing through the casing to operate water liftingmeans, which causes the airto pass through the water so, thatthe airiswashed and cooled, the invention eliminating pumps and other expensivemeans for spraying the water through the air.

The invention also consists in certain other features of construction,combination and arrangement of the several parts, to be hereinafterfully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claim.

In describing the invention in detail reference will be had to theaccompanying drawing wherein like characters denote'like orcorresponding parts throughout the several views and in which:

Fig. 1 is a longitudinal sectional view through one form of theinvention.

Fig. 2 is a'view looking towards the fan end of the device.

Fig. 3 is a view looking towards the other end thereof.

Referring to Figs. 1, 2 and 3, the numeral I indicates an elongatedcasing supported in any suitable manner, such as by the legs 2. A motor3 is centrally supported in the casing, adjacent one end thereof, by themeans I and the blades of a fan 5 are attached to the shaft of themotor. A screen 6, preferably covers this end of the casing. Alongitudinally extending shaft 1 is centrally supported in the casing,by the cross bars 8, the shaft extending from the motor to the other endof the casing. The shaft has attached thereto the disk 9, the major partof which is composed preferably of fabricated cloth or porous canvas, asshown at I ll. The shaft also has attached thereto a disk ll providedwith the inclined blades l2 and this disk also has its major portioncomposed of porous material as shown at E3. This disk II is spaced fromthe first disk and is located adjacent the end of the casing remote fromthe fan. Partitions l4 extend upwardly from the bottom of the casing andform a water chamber, into which extend the two disks, so that theporous material of the two disks will be saturated by the water as thedisks pass through the chamber.

Thus it will be seen that as-the fan rotates it will draw air throughthe casing and this air acting against the blades l2 will cause the diskI l to rotate and as said disk is attached to the shaft,

said shaft and the other disk} will be rotated and as the porousmaterial carried by the disks passes through the water, such materialwill be saturated with the water and thus the air passing through thematerial will be washed and cooled 5 by the water in the material and bythe water running down the material, as it is lifted thereby.

If desired, the blades may be shortened so they will not extend intothewater and furthermore the fan can be made to push the air through 10the casing, instead of pulling it through the casing, as shown in thedrawing.

Thus it will be seen that the invention provides an inexpensive airconditioning means which eliminates pumps and the like as the air forced15 disposed cylindrical casing partially-open at its 30 inlet end andfully open at its exit end, a water chamber in the lower portion of thecasing terminating short of the exit end thereoffcross bars securedwithin the casing transversely over the ends of the water chamber, arotatable shaft 35 mounted in the cross bars axiallyof the casing, openframes secured to the shaft adjacent its ends and extending into thewater chamber, porous material carried by said open frames for taking upwater from the water chamber during rota- 40 tion thereof, radiallydisposed inclined blades secured to the inlet side of one of the framesadapted to extend into the water chamber and to be rotated by incursionof air into the casing, a motor in the casing beyond the water chamber45 and in axial alignment with the shaft, brackets supporting the motorfrom the casing, and a fan of approximately the interior diameter of thecasing mounted on the outer end of the motor shaft with its bladesextending beneath the level 50 of the water within the water chamberwhen traversing the lower portion of the casing.
